The fluorocarbon-based polymer ethylene tetrafuoroethylene (ETFE) is quickly gaining popularity in North America and is being used on some of the continent’s most prominent projects. Through review of multiple case studies of current ETFE installations, Morrison Hershfeld will review lessons learned and provide an understanding of limitations as well as benefits of the material from a building science perspective.

This lecture will focus on the benefits of building in a dry, controlled environment and how this helps to build better buildings. Focusing on the science of construction, specifically the thermodynamic relationship of a building from inside to outside. Speaking on product integration and the importance of understanding how all the different WRBs, tapes, and sealants work together as well as the importance of mechanical systems and building pressures.

In the last decade, carbon levels increased 20 parts per million (from 380 to 403), the population grew by one billion, global temperature increased by half a degree Celsius, and 25 percent more people moved into our cities.

Multnomah County’s central courthouse was built between 1909 and 1914, when the county had only 250,000 residents and long before modern building code standards for the region’s risk of earthquakes were in place. The new Central Courthouse Project is a swiftly rising, 17-story-structure at Southwest First Avenue and Madison Street, and is slated for completion in the spring of 2020.

Sheet metal is a unique roof system choice that continues to evolve into new systems and applications. Metal roofs are gaining market share in both commercial and residential markets. Building owners have a high performance and aesthetic appeal expectation for metal roofs. Along with this evolution come the problems associated with it. This seminar is intended to provide a review of the top ten problems for metal roof designers. This will include a description of the problem, why it may occur, ramifications and how to prevent it through proper design.

This program addresses the importance of resilient building design and how it differs from green building design. It covers the resilient qualities of concrete masonry products and wall systems.

In this presentation, Richard will share the design principles being developed for the ASTM Structural Use of Glass standard, how they were implemented on the Seattle Space Needle, and how these new standards will allow architects and engineers to achieve bolder designs with lower risks.

Building envelope standards and practices have evolved over the past few decades in response to increased energy efficiency goals and a better understanding of Building Science. New materials, systems, and methods have been developed that reduce air leakage through building envelopes. Thermal protection requirements have increased and continuous insulation is often detailed better to avoid thermal bridges.

The building envelope is an integral part of architectural expression and is quickly becoming the innovative system utilized to realize carbon emission reduction goals. More and more the building envelope’s roofing, glazing, and waterproofing assemblies include Mass Timber. These assemblies are critical for ensuring durability but challenged to increase envelope performance without creating environmental barrier deficiencies.
